Generalized linear model with four predictors
- Swell height, period and direction
- Tidal height
\[ Rides_{i} = Poisson(\mu_{i}) \]
\[ E(Rides_{i}) = var(Rides_{i}) = \mu_{i} \]
\[ log(\mu_{i}) = \alpha + \beta_{h}Height_{i} + \beta_{p}Period_{i} ~+ \]
\[ \beta_{d}Direction_{i} + \beta_{t}Tide_{i} \]
